68-微信公众号开发涉及到的token和access_token

1. 基础支持的access_token

官方文档：

https://developers.weixin.qq.com/doc/offiaccount/Basic_Information/Get_access_token.html

实现：

CommonConstant.java:

String WXGZH_TOKEN_URL = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=%s&secret=%s"; String WXGZH_SNS_OAUTH2_ACCESS_TOKEN_URL = "https://api.weixin.qq.com/sns/oauth2/access_token?appid=%s&secret=%s&code=%s&grant_type=authorization_code"; public JsonResponse getToken(String appid,String secret){ String token = (String)wxgzhCommonCache.getBaseToken(appid); if(StringUtils.isEmpty(token)){ String url = String.format(CommonConstant.WXGZH_TOKEN_URL,appid,secret); String result = okHttpUtil.get(url); if(result==null){ logger.info("result is null"); return result(-1,"获取token失败",null); } JSONObject resultObj = JSON.parseObject(result); if(resultObj==null){ logger.info("result is null"); return result(-1,"获取token失败",null); } String errcode = resultObj.getString("errcode"); if(StringUtils.isNotEmpty(errcode)){ logger.info("获取token,返回错误,result={}",result); return result(-2,"获取token,返回错误",resultObj); } token = resultObj.getString("access_token"); int expires_in = resultObj.getInteger("expires_in"); expires_in = expires_in-300;//预留5分钟 wxgzhCommonCache.putBaseToken(appid,token,expires_in); } return result(0,"",token); }

2. 网页授权需要获取的用户access_token

官方文档：
https://developers.weixin.qq.com/doc/offiaccount/OA_Web_Apps/Wechat_webpage_authorization.html
代码实现：

public JsonResponse getAccessToken(String code){ String url = String.format(CommonConstant.WXGZH_SNS_OAUTH2_ACCESS_TOKEN_URL,appId,appSecret,code); String result = okHttpUtil.get(url); JsonResponse js = checkResult(result,"获取access_token"); if(js.getCode().intValue()!=0){ return js; } return js; }
